- to improvements in locks wherein a pairy of doors mounted to swing in a common opening may be simultaneously locked to one another and to an adjacent wall-- In a more specic aspect, the invention re-l m lates toa formy of locking mechanismwhere- Yin latch bolts are provided at the end of a door'to engageavwall of a wardrobe or the like, and at the Vfree edge of the door to engage an adjacent door, while a common bolt operating mechanism is provided at a convenient height, the bolts and operating mechanism being carried on an interior Side ofthe door andA hidden fromview.

' object of the invention is to provide a 'locking mechanism of the abovecharacter having aplurality of bolts, in which each bolt maybe retracted independently by en-` gagement with a strike. y

Afeature of the inventionresides in a relatively simple form of actuatingmechanism for rctracting a plurality of bolts by a single operating member.-

To these and other ends, the invention consists in the Vnovel featuresand combination of 4parts to be lh ereinai'ter described and claimed.

`Referring tothe drawings in whichI have illustrated my inventionnby showing a pre- -`150 ferred embodiment of the same, the reference spindle 19.

numeral 1,0 indicates,in general, adoor frame of a wardrobe or the like having hingedly rmounted on the opposite sides thereof'a pair of doors 11 and 12, thefree edges 13 and 14 of which abut when the doors.' are in closed 65 position. vSeated in door l1 and yflush with the inner face 15 and free edge 13 thereof, and at a convenient height from the bottom of thevwardrobe, isa lock case 16 having in the linner wall 17 thereof an opening 18 for 60 the.x yreception of a spindle V19 extending through the `opening 18 towardsthe exterior of the rdoor and provided with one or more tongue's20, which are received lwithin a similar number of recesses 21 in shank 22 of knob 5. f

23, knob 23 being mounted at the exterior of the door 13 in escutcheon 24, and beinfrheld against movement in anl axial direction in escutcheon 24 by shoulder 25 bearing against the outer face 26 of escutcheon 24,y and split 7o y ring 27 receivedin groove 28 in knob shank 422 kand bearing against an interior face 29 of the escutcheon. Escutcheon 24 is held on door 13 by means of a yplurality of screws 30 which pass through thedoor 13 from the in- 75 terior thereof into the escutcheon.l

Lockcase16`is provided with a cover plat 31 secured by means of screws 32 to the main body of the case 16 and passing through cover plate 31and into door 13 are screws 33 which 80 secure the lock case 16 to thedoor. Cover plate 31 is provided Withan opening 34 in axial alignment with spindle-19 and mounted in opening 34 is a thumb turn 35 havingl a reduced end 36 received within a counterbored S5 opening 37 in spindle 19 to hold the latter Vagainst axial movementyin opening 18,.out

ward movement of thumb turn 35 through opening 34 being prevented by shoulder 38 which bears against the interior surface of 90 cover plate 31. Relative rotational movement of thumb turn and spindle 19 is prevented by arm39 on thumb turn 35, which is received between shoulders 40 and 41k on Mounted at the upper edge of door 13 and flush with the inner surface thereof is a latch bolt case 42'having an open face applied to the recess in the door, latch bolt case 42 being secured to door 13 bysuitable means, as for eXample screws 43. The reference numeral 44 indicates a rod extending between case 16 and latch bolt case 42, rod 44 being supported in an opening 45 in a lower part of case 42 and having mounted on the upper end thereof a latch bolt 46, latch bolt 46 being provided withran arm 47 throughwhich the rod 44 passes, and an opening 48in which the end of rod 44 is received. Latch bolt 46 is constantly urged into protracted position by means of compression spring 49 mounted on and surrounding rod 44 and having one end bearing against a part of case 42, while the other end bears against arm 47.

Latch bolt 46 is reeto move in an axial direction'onvrod 44 and is movedinto retractedpositionby means of., pin 50 extending transversely through rod 44 and engaging an u-pper face of arm 47 inward or retracted movement of. latch bolt 46 being limited by post 51 on case 42. The head 52 of latch bolt 46 is preferably rectangular in cross-section and is received within a similarly shaped opening in the upper end of case 42, head 52 being provided with a beveled `or inclined face 53 which cooperates with a strike 54 on the adjacent door frame to retract the bolt, strike 54 being provided with a bolt receivingopening 55 and a downwardly extending arm 56 which limits the movement of door 13 in closing. c

The lower end of rod 44` is threaded, as at 57,` and mounted on the threaded end 57 isa cross-head 58, supported between anges 59 and 60, and connected by a pivotal stud 61v to a link 62 which isV pivotally connected at 63 to arm 64 ofy spindle 19', movement of spindle 19 in one directionbeing limited by post 65 on casing 16. V

V The mechanism described up to this point is suitable for latching a door to a door casing or the like, and its operation may be briefly described as follows: Assuming the parts of the lock-mechanism to be in the position shown in Figs. 3 and 4, rotation of handle 23 will rotate spindle 19 and through the medium of link 62 will cause cross-head 58 to descend, carrying latch bolt 52 with it, and withdrawing the latter from the strike receiving opening 55 in strike 54. The door is now free to open and-may be swung on its hinges by means of knob 23. When the knob 23 is released, the spring 49 will return the `knob 23, spindle 19, link 62, rod 44, and latch bolt 52 to their original position in which latch bolt 52 .is protracted. If the door is vnow closed, it will be unnecessary to rotate Vto be operated.

may be latched together at the same time one of the doors is latched to a door casing. As a preferred means to this end, a latch bolt 66 is mounted in case 16 between posts 67 and 68, bolt 66 having a preferably rectangular head 69 received in a rectangular opening in wall 70 of casing 16 and urged into protracted p0- sition by means of compression spring 71 mounted in a recess 72 in bolt 66 and having one endbearing against the bolt at the end of the recess, while the opposite end bears against post 7 3 on casing 16. The outer end o bolt 66 may be beveled in the usual manner, while at its inner end a lug 74 is provided which may be engaged by an arm 75 of belt crank. lever 76, lever 76 having a subn stantially cylindrical pivotal bearing part 77 received in socket 78 in case 16, while the other arm 79 of lever 76 is received undei` cross-head 58. Bell crank lever 76 is held in socket 78 by skirt 80 `which when the lock is assembled bears against flange 59.

It will be readily understood that as the cross-head 58y is moved in a downward direction by link 62, through the rotation of spindle 19 and knob 23, the cross-head 5S engages arm 79 of bell crank lever 76 and rotates the latter about bearing part 77, arm 75 of bell crank lever 76 Yengaging lug 74 onV bolt 66 and retracting the latter against the compression of spring 71. Upon the handle 23 being released, springs 71 and 49 cooperate to restore the lock mechanismto protracted position. It will' be noted that bolts 46 and 66 may be retracted by engagement of their respective beveled heads with the strike plates on the door frame independently, and in each instance it will be unnecessary for the latch retracting mechanism From the above description of the nature of my invention and the preferred embodimentof the same, it will be readily Seen that I have provided a relatively simple form of lock mechanism wherein a pair of doors may be lockedV to one another and to a door frame by a single locking mechanism.

While I have shown and described a preferred embodiment of my invention, it will `be understood that it is not to be limited to all the details shown but is capable of modiiication and variation within the spirit of the invention and the scope of the appended claims.

What I claim is z 1. In a wardrobe lock, a lock casing, a cross-head mounted in said casing, a latch bolt remote from said casing, a connection between said latch bolt and cross-head, an operating lever for said cross-head in said cas-ing, a link connecting said lever to said cross-head a latch bolt in said lock casing, and a bell crank lever in said casing having one arm in operative engagement with the second-named latch bolt and the other arm in operative engagement with the crosshead, whereby upon actuation of the crosshead by the operating lever the secondnamed latch bolt is actuated.

2. In a wardrobe lock, a lock casing, a cross-head mounted in said casing, a latch bolt remote from said casing, a connection between said latch bolt" and cross-head, an operating lever for said cross-head in said casing, a connection between said lever and said cross-head for reciprocatingthe latter upon rotation of the lever, a latch bolt in said lock casing, a bell crank lever in said casing having one arm in operative engagement wit the second named latchbolt and the other arm in operative engagement-with the crosshead, whereby on actuation of the cross-head by the operating lever the second named latch bolt is actuated.
